Seducing and locking lips with Sofia Boutella wasn't tough for Charlize Theron, because she thinks the French actress is "gorgeous".

Footage of the two leading ladies' rough lesbian sex scenes in the trailer for new film Atomic Blonde raised eyebrows and temperatures when it was released online on Friday (10Mar17).

In the teaser, Theron's Lorraine Broughton beats up handfuls of men in amazing action sequences and then seduces Sofia's spy in a very sexy scene, as the women roll around in just their lingerie.

The 41-year-old actress admits romping around with Sofia, 34, was a great day at work.

"Seducing her, it's very easy, she's gorgeous!" Theron told Canada's Entertainment Tonight. "She was just great. She was the only actress that we looked at.

"She came over, she hung out with me and (director) Dave (Leitch) and there was something about her that was so genuinely innocent and yet incredibly strong, that she was really perfect for the film.

"I can't imagine anyone else doing it. She's a dancer, I'm a dancer. So, we're a little bit like - you know dancers are like... Being naked is nothing. We just wanted it to be real and cool."

And Charlize can't wait for fans to see her play another strong female - the roles she is drawn to.

"I think they're all very vulnerable too," she told ET. "I think great strength comes from women who can be vulnerable and look at their weaknesses and find their strengths from that. I think you almost have to be incredibly vulnerable and weak in order to find strength, to survive something. I think that's what I love so much about these women."
